This report is a result of the final project of the authors’ Master of Science degree in Ergonomic design and production. The project was performed at Schefenacker vision system in Adelaide, Australia, during the autumn semester of 2006. The aim of the project was to develop a concept of a multi functional switch panel, that can be used in the next generation cars. The concept was developed by using the systematic problem solving method. To achieve the most suitable product, CAD software such as Catia V5 and rapid prototyping methods were used. As a part of the project a great study was made to investigate what functions the users demand and what the next trend on the market will be. To evaluate the users preferences a product test on existing switches where made. The test evaluated the style, clarity, sound and push feeling. The information gathered where used as basis for the design of the concept. To clarify the problems and the users, personas based on the information gathering where created. A lot of effort was put to achieve a good tactile feel and HMI. To get the best possible placement, the car interior of a 2008 car from a major manufacture was set up in the cad software Catia V5 where view angels and the best position for the hand were tested As soon as the structure of the menu was created a simulation was made in Macromedia Flash 8. The simulation gave the possibility to test the interface during the development. The style of the concept was developed by using sketches, clay models and CAID softwares, ALIAS studio tools and Maya. The project resulted in a physical prototype that was painted to get a realistic look. The prototype had a working mechanism.
